Standard Practice for Describing Photomultiplier Detectors in Emission and Absorption Spectrometry
ORDER

Scope

1.1 This practice covers photomultiplier properties that are essential to their judicious selection and use of photomultipliers in emission and absorption spectrometry. Descriptions of these properties can be found in the following sections:

Precautions and Problems6
General6.1
Fatigue and Hysteresis Effects6.2
Illumination of Photocathode6.3
Gas Leakage6.4
Recommendations on Important Selection Criteria7

1.2 Radiation in the frequency range common to analytical emission and absorption spectrometry is detected by photomultipliers presently to the exclusion of most other transducers. Detection limits, analytical sensitivity, and accuracy depend on the characteristics of these current-amplifying detectors as well as other factors in the system.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
